Changelog

postgresql-15 (15.3-0+deb12u1) unstable; urgency=medium

  * New upstream version.

    + Prevent CREATE SCHEMA from defeating changes in search_path
      (Report and fix by Alexander Lakhin, CVE-2023-2454)

      Within a CREATE SCHEMA command, objects in the prevailing search_path,
      as well as those in the newly-created schema, would be visible even
      within a called function or script that attempted to set a secure
      search_path.  This could allow any user having permission to create a
      schema to hijack the privileges of a security definer function or
      extension script.

    + Enforce row-level security policies correctly after inlining a
      set-returning function (Report by Wolfgang Walther, CVE-2023-2455)

      If a set-returning SQL-language function refers to a table having
      row-level security policies, and it can be inlined into a calling query,
      those RLS policies would not get enforced properly in some cases
      involving re-using a cached plan under a different role. This could
      allow a user to see or modify rows that should have been invisible.
